CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 463,925, dated November 24, 1891.

Application filed May 6, 1891. Serial No. 391.800. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM PALMER SIMP- soN,a citizen of the United States, residing at Nelsonville, in the county of Marion and State of Missouri, have invented certain new and useful Improvements in (Jar-Couplers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in a new and improved automatic car-coupler which will antomatically couple two cars together and which can be uncoupled without going between the cars; and the invention will be hereinafter fully described and claimed.

Referring to the accompanying drawings, Figure 1 is a perspective View of the end of a car provided with my invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 shows a slightly-different arrangement of the uncoupling-lever.

The same letters of reference indicate corresponding parts in the several figures.

Referring to the several parts by letter, A indicates the draw-head, which is formed with the usual horizontal opening a and the vertical apertures a for the reception of the coupling-pin. To the rear of the horizontal opening a, but communicating with the same, is formed the curved vertical opening B.

0 indicates a curved metal tumbler or piece, the curve of which is greater than that of the are of a circle, and this piece Cis centrally pivoted in the upper part of the curved vertical opening I on a transverse pivotbolt D. To the upper forward end of the piece C is pivoted the upper end of the coupling-pin E.

Upon the top of the car, at the end thereof, is mounted in bearings f a rock-shaft F, having a handle F at its outer end for convenience in turning it. To a short arm F of the rock-shaft is secured the upper end of a connecting-chain G, the lower end of which is pivotally connected by a stirrup G with the upper outer end of the tumbler C. It will now be seen that when the handle F is drawn back the chain G will raise the outer end of the piece 0, thus raising the coupling-pin into the position shown in Fig. 2, so

as to free the end of the link, and thus nn couple the two cars. At the same time that the link is thus raised the lower end of the curved piece 0 swings up through the lower part of the vertical opening B into the inner end of the horizontal opening a, coming in contact with the inner end of the link and sliding the same out of the draw-head as the pin is raised to free it. The parts stand in this position, as shown in the sectional view, Fig. 2, when the cars are brought together to couple them, and as the end of the link of the other car enters the opening a it will come in contact with the lower end of the piece 0, which is then standing at an angle, and as it presses against the same it will swing the pivoted are 0 down, swinging the coupling-pin down through the vertical opening a, thus automatically locking the link in the draw-head.

From the foregoing description, taken in connection with the accompanying drawings, the 7 construction, operation, and practical advantages of my new and improved carcoupler will be readily understood. It will be seen that my new and improved car-coupler is'very simple and strong in its construction, being composed of unusually few parts. It is therefore devoid of any complicated mechanism, which would be liable to break and get out of order, and is exceedingly convenient, rapid, and effective in its operation.

In Fig. 3, instead of the rock-shaft F, I employ the pivoted L-shaped lever H, the upper end of the connecting-chain G being attached to the inner end of the outwardlyprojecting arm 11 of this lever. At the lever end of the rock-shaft F, I mount the bracketsf and f, the former being secured directly to the roof of the car and the latter affixed to the corner thereof. The bracket f is L-shaped at the end adjacent to the levet and square at the other, presenting, when in position, an inclined face upon which the lever F may rest. The bracket f, being secured at the corner of the car, is directly in the path of the outward swing of said lever and is adapted to hold the same in an inclined position, ready for the hand of the operator.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

In a car-coupler, the combination of the in the path of the lever F and adapted to draw-head formed with the openings a a support the same in an inclined position, as and having the curved vertical opening B, set forth. the curved tumbler O, centrally pivoted in Intestilnony whereofIaflixinysignnture in 5 the upper part of the curved opening B, the presence of two witnesses.
